NT1 Rear Swing Shaft, Direct-Fit XN1-14 by 3Racing  [XN1-14]

Overview of the NT1 rear shaft

The XN1-14 rear swing shaft is intended as a direct replacement for the XRAY NT1 touring car rear pivot. It serves as the main axle for the rear swing arms and is used when repairing impact damage or swapping out worn hardware.

Fit and function: designed to interface with NT1 rear suspension mounts and linkages, this shaft restores the intended pivot axis and allows normal swing arm movement while preserving factory suspension geometry.

Installation notes: access the rear bulkhead and remove the swing arm assembly as per your chassis maintenance steps, extract the damaged shaft, then fit the new unit making sure it seats correctly and retaining clips or fasteners are installed per your NT1 parts layout. Test for binding and clearance before track sessions.

Tuning role: replacing a fatigued or bent shaft helps the rear end return to predictable roll and damping response, simplifying setup changes and lap-to-lap consistency.
